I talk to Randy Stein, who has researched the Myers Briggs and personality tests in general. Topics discussed include: the reasons people object to the Myers Briggs test; the downsides of personality tests that group people into boxes (as opposed to using a spectrum-like approach); the Forer effect, where people often believe that vague descriptions apply to them; the downsides of labeling ourselves and others; how the complexity of a question can wrongly seem like deepness; how Myers-Briggs relates to the more scientifically respected "Big Five" personality traits. We also talk about Randy's research on political polarization, showing how we can be drawn to being the opposite of a disliked group.
